Forwarding strategy on SDN-based content centric network for efficient content delivery

— Content Centric Networking (CCN) paradigm has been proposed to solve the problems of current Internet Protocol (IP) communication. However there is one significant drawback in existing CCN, which is that interest packets are broadcasted to all over the network. This may not only result in slow in delivery of data but it is also causing a lot of network traffics due to a large number of interest packets. For this reason, it is obviously not suitable in a large-scale network. To address the problem we propose a novel packet forwarding strategy using Software Defined Networking (SDN) controller and application. There mainly consists of two processes in CCN. One is for interest packets and the other is for data packets. In this paper, we show how the forwarding mechanisms for the two types of packets are operated under SDN-based CCN in order to improve the efficiency of content delivery and utility of network resources.
